PLA'STERER?S S'TEELANGLEMTIE.

SPECIFICATION forming part of Letters Eatent No. 608,888, dated August 9, 1898. Application filed July 13,1897. Serial No. 6%,456. (N0 model.)

To all whom it may concern.-

Be it known that I, GEORGE W. MESERVE, a citizen of the United States, residing at Boston,in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Plasterers Steel Angle-Ties, of which the following is a specification, illustrated by the accompanying drawings.

My invention relates to improvements in angle-ties to be used by plasterers to prevent cracking of plastering of the inner corners of rooms where brick and wooden partitions meet and where ceilings abut against brick walls.

Figure 1 represents the sideof a room in brickwork and the cross-partition and ceiling in woodwork, lathed and fitted with my perforated steel angle-tie, ready for plastering.

Fig. 2 is a cross-sectional view of Fig. 1, showing the angle-tie, lathing, studding, and brickwork. Fig. 3 is perspective View of a short section of perforated sheet steel angle-tie having a lateral bend of about ninety degrees. Fig. 4 represents a short section of a wovenwire angle-tie bentlaterally near the center at right angles adapted to be secured to a wooden lathing by one wing and hang free against a more firmly built wall by the other.

Fig. 1 represents an angle which seldom fails to split apart. The firm wall on one side and flexible partition on the other, so often necessary in low-cost buildings, is poor construction at best.

Trembling floors, jarring partitions, and shrinkage of woodwork are not to be'resisted by nails or spikes. All I attempt to do in this case is to hold the'plastering together. If thecrack must come, let it be back of the plastering. The common angle is held together by the mortar alone, which is but threeeighths of an inch thick. By reinforcing the mortar with perforated sheet-steel it becomes the strongest part of the wall. This is done by bending the perforated metal laterally to conform to the angle and nailing one wing to the Wooden partition firmly, leaving the other free on the wall, so that thestrain takes the mortar bodily from the brickwork and the cracks will be back of the plastering, out of sight.

The methods and improvements herein illustrated and described have been brought out and demonstrated by long and costly experiments. My endeavor to enable the plasterer to do what he never could do before has been accomplished in this way.

That I claim as my invention, and desire to secure by Letters Patent, is-

The herein-described perforated and laterally-bent steel corner-plate, made to conform.

to the outline of a reentrant angle in combination with a'brick wall and a Wooden partition or ceiling, to which one wing of said plate is secured, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 24th day of June, A. D. 1897.

GEORGE WV. MESERVE.
